Filed Sept. 27, 1935 0 H1 Z v Z. lo w xNvENToR y Patented May 25, 1937 UNITED ST ATE-NT (DFF ICE 5 Claims.

This invention relates to buttons, more particularly that type of button known as tack buttons which are secured to the cloth by passing a tack or rivet through the cloth into the iront of the button, the end of the tack being then vspread or clinched within the button to secure it to the cloth.

It is the main object-of the invention to provide a button of the character as indicated which shall be eicient in operation, easy to install in place upon the goods and shall be of rugged and frm construction.

A further and more specific object of the invention is to provide an increased and more stable contacting area between the housing portion and the anvil portion.

A further object of the invention is to provide a button of the character described wherein the anvil portion is of such a character that it may be readily adapted to any heighth of housing and still maintain its clinching or spreading qualities without altering the general design of the button.

Other and ancillary objects of the invention will appear hereinafter.

In the accompanying drawing which illustrates the invention:

Fig. 1 is a perspective view of a button embodying the invention in place upon a cloth, the latter being shown in section.

Fig. 2 is an enlarged axial section on the line 2-2 of Fig. 1.

Fig. 3 is an exploded Viewshowing in perspective the parts from which the button is formed; and

Fig. 4 is a perspective View of a modified form of tack or rivet.

Referring to the drawing, the button comprises a front I, an anvil 2, a housing 3 and a tack or rivet 4.

The front comprises a flat portion 5 having the marginal flange 6 at right angles thereto.

The anvil portion comprises the central projection comprising the cylindrical part 'I adjacent the base comprising the marginal portion or flange 8, the central projection having the conical end 9.

The housing part 3 comprises the housing por tion I0 having the marginal portion or flange II at right angles thereto, the housing portion IB being open at I2 at one end and having the smaller opening I3 at its other end.

The tack 4 comprises the head I4 from which extends the shank I5 in the end of which is the transverse slot I6 forming the prongs I'I.

In .assembling the button, the `flanges 8 and indicated bythe dotted line 22 in Fig. 2.

(Cl. 24e-95) II of the anvil and housing are placed'within the iront I, and the edge of the ange has its edge peened over the edges of the flanges 8 and I so that they are securely held together. `It will be observed that the `flanges II and 3 provide nat engaging surfaces' between the housing and anvil whereby these two parts have a broad, stable and firm bearing on each other, and the flat surfaced broad bearing between the anvil and the flat face 5 of the front produces a firm and secure engagement between the anvil and housing parts and the front so that when they are secured together by the peening over of the edge I8 on the front a rugged and firm construction is obtained. y 15 In assembling the partsras described, it will be seen that the central projection of the anvil telescopes within the housing portion It with a clearance `I9 between it and the housing. Further, the provision of the conical spreading end 20 on this projection withi a cylindrical portion 'I between the conical portion and the base of theA anvil, provides a construction whereby the desired inclination of the conical portion may be made such as is best to produce the bestresults in spreading the tack, and this may be located atany point desired Withinvthe housing by making the cylindrical portion 'I of the projection of the desired length. Without such a cylindrical portion a change in the distance of the spreading point of the projection from the base of the anvil would necessitate a change in the inclination of the comb within the permissible limits of the size of the button.

The anvil front and housing having been as sembled as described (and as shown in Fig. 2) the button is secured to the cloth 20 by inserting the tack as shown in Fig. 3 through the cloth, with its head I4 on the opposite side thereof from the button, and this pronged end entering through the hole I3 of the housing and the point of the projection 9 engaging in the slot It between the prongs of the tack. The tack and the remainder of the button are then forced together when the prong I'I of the tack would be spread as shown in Fig. 2 when the housing and its secured parts will be securely clamped to the cloth. The parts are preferably of such dimensions that in securing the button to the cloth as described the prong Il will be spread to such an extent D as to bite into the walls of the housing portion I0. The firmness andl stability of the securing of .the button is thereby enhanced.

If desired, vthe anvil may be made hollow as Referring to the modified form of tack as shown in Fig. 4, there is therein shown a tack which instead of having its shank slotted to form prongs as shown in Figs. 2 and 3, the shank I5' of the tack of Fig. 4 has a central bore 2|. When this tack is used in an assembly such as shown in Fig. 2 the point of the anvil cone 9 enters within the bore 2l and the portions of the shank surrounding the bore are spread outwardly, as the tack is forced toward the anvil, in much the same manner as the prongs Il are spread, so that the button is secured to the cloth in a similar manner.

While the invention has been illustrated in what are considered its best applications, it may be embodied in other structures without departing from its spirit and is not therefore limited to the structures shown in the drawing.

What I claim is:-
